KROHNE OPTIMASS 2400 Manual de usuario

For initial set up, we strongly recommend that you also refer to the relevant manual!

Quick Start

Installation, assembly, start-up and maintenance may only be performed by appropriately

trained personnel. Check the nameplate for correct operating conditions.

For use in hazardous areas, special codes and regulations are applicable. Instruments must

not be connected to power supply before reading instructions described in the supplementary

manual.

This instrument complies with the requirements of the Pressure Equipment Directive. Please

refer to the nameplate for operating condition limits. Instruments must not be pressurised

before reading instructions described in the manual.

This instrument complies with the requirements of the Low Voltage Directive. Instruments must

not be connected to the power supply before reading the instructions described in the manual.

For devices used in SIL applications, additional safety notes apply. For detailed information

refer to the “Safety Manual”.

The responsibility as to the suitability, intended use and corrosion resistance of the used

materials against the measured ﬂuid of this device rests solely with the operator.

Special conditions of use to be observed

• The OPTIMASS measuring system and MFC converter must be included in the equipoten-

tial bonding system of any hazardous area installation.

• Allow the electronics to de-energise before opening the electronics enclosure inside a

hazardous area. The time needed to de-energise is 35 minutes for temp. class T6 and 10

minutes for Temp. class T5. There is no waiting time for Temp. class T1

• Use certiﬁed cable glands on cable entries. Use a certiﬁed plug to seal unused cable

entries.

• Install connecting cables as ﬁxed wiring so that they are protected against damage.

Connecting cables must not exceed the parameters speciﬁed in the Supplementary

Instructions for Hazardous Areas.

• For details on the relationship between: maximum permissible ambient temperature, maxi-

mum medium temperature, maximum surface temperature and the relevant temperature

class for each individual meter, please refer to the tables provided in the relevant meter

Handbook and/or the Supplementary Instructions for Hazardous Areas.

If the hygienic installation requires the meter to

be self draining, mount the meter at an angle.

DO NOT mount the meter horizontally!

Twin, straight tube mass ﬂowmeter

CAUTION!

If there is excessive vibration in the process pipework, you must isolate the meter from its

mounting. It is recommended that you place an insert made from rubber (or similar material)

between the meter body, or pipework, and the mounting clamp or ﬁxing point. For more

information, contact the manufacturer.

Danger:

• Turn oﬀthe power supply before working on electrical connections.

• Check the voltage data on the nameplate

• Observe national regulations for electrical installations

• The device MUST be grounded in accordance with regulations to protect personnel

against electric shock

Vibration from pumps and other equipment in the process line can have an eﬀect on the meter that, in

some situations, can cause damage. Damage is most likely to occur if the meter has hygienic

connections and the level of vibration is excessive.

Signal cable preparation

The signal cable is made up of ﬁve (twisted) pairs of cables. Each pair also has a drain wire and the

three wires are covered in a foil wrap. The ﬁve cable pairs are covered in an outer foil wrap and a braided

screen. The complete cable is protected by a PVC outer sheath

3Outer foil wrap

4Foil wrap

5Cable pairs

6Drain wires

Strip back all the foil wraps and discard them. Unwrap the braided screen so that it can be twisted to form

a connection underneath the earth clamp. Bend all ﬁve drain wires back and twist them together with the

braided screen.

It is important that ALL ﬁve drain wiresAND the braided screen form part of the shielding.
